Baby's high-chair with foldable structure

Abstract

The high-chair has a base stand constituted by two mutually foldable arms. A chair-like body is slidably supported on one of the arms and has a back which is rigidly associated with guiding elements for sliding on the related arm. A seat is hinged to the back and is in turn hinged to a foot-rest which can be folded, together with the seat, toward the back. Elements are provided for releasably locking the chair body onto the related arm and allow a continuous sliding of the chair body on the arm for movement in the direction of lifting the chair body and, in discrete and successive portions, for movement in the direction of lowering the chair body.

I claim: 
     
       1. Baby's high chair with foldable structure, comprising; a base stand constituted by mutually foldable arms including a front arm and a rear arm;   a chair body slideably supported on said arms;   a back rigidly connected to said chair body;   guiding elements rigidly connected to said back and slideably mounted on said arms;   a seat hinged to said back;   a foot-rest hinged to said seat and foldable toward said back;   releasable locking means for releasably locking said chair body on one of said arms, said releasable locking means being adapted to allow a continuous sliding of said chair body on said one of said arms for movement in a direction of lifting said chair body, and in discrete and successive portions for movement in a direction of lowering said chair body; wherein said releasable locking means comprise;     opposite inner faces defined on said front arm;   guiding tracks provided on said opposite inner faces;   an actuation body oscillatably mounted on said chair body;   pins defined on said actuation body and engaging in said guiding tracks, and wherein said guiding tracks define a substantially longitudinal extension having opposite longitudinal edges, said opposite longitudinal edges having a saw-tooth shape defining peaks, said peaks of said opposite edges being arranged mutually offset, whereby a peak of one of said opposite edges is arranged between two peaks of another of said opposite edges.     
     
     
       2. Baby's high-chair, according to claim 1, wherein said actuation body defines a pivoting point, said pins comprising a pair of pins arranged diametrically with respect to said pivoting pins of said actuation body and insertable in said guiding tracks, recesses defined by said peaks at said opposite longitudinal edges of said guiding tracks, said pins having between one another a distance which is greater than the distance between two flanking peaks and smaller than twice the distance between said two flanking peaks so as to engage in said recesses. 
     
     
       3. Baby's high chair comprising; a front arm;   a rear arm pivotally connected to said front arm;   a chair body slideably supported on said front arm;   a back connected to said chair body;   guiding elements connected to said back and slideably mounted on said arms;   a seat hinged to said back;   a foot-rest hinged to said seat and foldable toward said back;   guide means provided on said front arm;   recess means defined by said guide means;   an actuation body oscillatably mounted on said chair body;   pin means defined on said actuation body and engaging said guide means; said pin means being continuously slideable along said guide means in a direction of lifting said chair body, said actuation body being oscillatable on said chair body for successively engaging said pin means in said recess means during movement along said guide means in a direction of lowering said chair body.     
     
     
       4. Baby's high-chair according to claim 3, wherein said guide means comprise a guiding track provided on opposite inner faces of said front arm, said guide track having a saw tooth configuration defining peaks, said recess means comprising abutment recesses defined between said peaks. 
     
     
       5. Baby's high-chair according to claim 4, further comprising an inclined guiding plane extending from each one of said abutment recesses to a successive one of said peaks. 
     
     
       6. Baby's high-chair according to claim 3, wherein two actuation bodies are oscillatably mounted on said chair body, said two actuation bodies being interconnected by a U-shaped lever having a crosspiece, said chair body having connected thereto a bracket, said crosspiece being releasable engageable with said bracket. 
     
     
       7. Baby's high-chair according to claim 3, further comprising a resting crosspiece, cavities defined in said resting crosspiece, end pins defined on said front arm and being releasably insertable into said cavities. 
     
     
       8. Baby's high-chair according to claim 3, wherein said chair body further comprises lateral uprights partially embracing said front arm, said back being connected to said lateral uprights, a seat pivotally connected to and superimposable on said back, and side walls connected to said uprights and arranged laterally with respect to said seat. 
     
     
       9. Baby's high-chair according to claim 3, wherein said seat has a transverse tab, and wherein said chair body defines a seat coupling region, said transverse tab abutting said seat coupling region. 
     
     
       10. Baby's high-chair according to claim 3, further comprising a resting crosspiece pivotally connected to said sides and foldable against said back beneath said foot rest. 
     
     
       11. Baby's high-chair according to claim 3, wherein said guide means comprise guiding tracks defining a substantially longitudinal extension and having opposite longitudinal edges, said opposite longitudinal edges having a saw-tooth shape defining peaks, said peaks of said opposite edges being arranged mutually offset, whereby a peak of one of said opposite edges is arranged between two peaks of another of said opposite edges. 
     
     
       12. Baby's high-chair according to claim 11, wherein said actuation body defines a pivoting point, said pin means comprising a pair of pins arranged diametrically with respect to said pivoting point of said actuation body and insertable in said guiding tracks, recesses defined by said peaks at said opposite longitudinal edges of said guiding tracks, said pins having between one another a distance which is greater than the distance between two flanking peaks and smaller than twice the distance between said two flanking peaks so as to engage in said recesses.
